Rotor Pump/Rotary Lobe Pump
Working Principle
Lobe pump is self-priming, valveless positive displacement pump. Through the two parallel shafts in the synchronous gear
to driven the rotor synchronous operation, chamber form a vacuum between the rotor vanes and casting surrounding, so
that the medium was inhaled, then displaced through the discharge-side. Pump operating direction can be reversed by 
changing the direction of rotor rotation, to be a two-way pump for reversing operation.

Rotor
Lobe pump manufacture use high precision 5-axis CNC machining. Our rotor perfectly seal with the inlets and outlets chamber,
pump suction ability can reach to 9 meters. The material of the rotor can be selected according to the characteristics of 
conveying medium. We have many kinds of rotor material for selection, including anti-wear elastomers, hard steel,
stainless steel and etc.

Space Occupied
Our lobe pumps design is compact, can be installed in extremely limited space. The design of flange and placement of the 
motor can be adjusted to fit for the customer's space constraints.

Pump Body
Pump body choose inblock casting, the error is minimal. Body material can be cast iron and stainless steel. Chamber inside
have replaceable protective liner. The liner surface can be hardened to increase wear resistance.

Simple Maintenance
Our lobe pump is unilateral shaft support design, fluid chamber can be quickly disassemble. Rotors and other accessories can 
be replaced in a few minutes without remove the pump inlet and outlet pipes. Also lobe pump have few wearing parts, it make
lobe pump lower shutdown time and lower using cost.

Operating Efficiency
Very high efficiency, about 60% to 85%.

The Particles Size
Lobe pump have wide fluid chamber, no block problem.

Self-priming and Dry Running
Lobe pump have good self-priming ability, reach to 9.5m, and can allow a certain time dry running.
